The key to good woobles is the cup the purple one has the best cup in the blade try tapering it more towards the bottom like the top remember the water has to hit a curved surface to create a up-set ,but needs to was off at the same rate You can tune it by bending one side of the lip in or out to get it to run true. Looks good!Also the blade needs to be further back in the head the eye being behind or slightly in front creates instability and won't let the bait stear itself.
